Given three dictionaries, associated with the variables, canadian_capitals, mexican_capitals, and us_capitals, that map provinces or states to their respective capitals, create a new dictionary that combines these three dictionaries, and associate it with a variable, nafta_capitals.

The Python code is explained below

Explanation:

#Define the dictionary

#canadian_capitals.

canadian_capitals = {

   'Alberta': 'Edmonton',

   'British Columbia': 'Victoria',

   'Ontario': 'Toronto',

   'Manitoba': 'Winnipeg'

}

#Define the dictionary

#mexican_capitals.

mexican_capitals = {

   'Puebla': 'Puebla',

   'Sonora': 'Hermosillo',

   'Tabasco': 'Villahermosa',

   'Hidalgo': 'Pachuca'

}

#Define the dictionary

#us_capitals.

us_capitals = {

   'Alabama': 'Montgomery',

   'Alaska': 'Juneau',

   'Georgia': 'Atlanta',

   'California': 'Sacramento'

}

#De-hash the values of

#the dictionaries using

#the **operator and add them

#to the dictionary nafta_capitals.

nafta_capitals = {**canadian_capitals, **mexican_capitals, **us_capitals}

#Print the dictionary

#nafta_capitals.

print(nafta_capitals)
